Hi  
Binomial Probability:  n = 30, p = 3/30 = .1
what then is the probability that the inspector's sample contains:
Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus
P( x = 0) = .0424
0r
{{{P (x)= highlight_green(nCx)(p^x)(q)^(n-x) }}} 
 P(0) = 1(.1^0)(.9^30) = .0424

P(x  ≥ 1) = 1 - P(x = 0) = 1 -.0424 = .9576
Wish You the Best in your Studies.
